BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, one embodiment of the invention will be described with reference to the drawings.

FIG. 1 is an external appearance view of such a state that a foldable type portable communication terminal apparatus, which relates to a first embodiment of the invention, was folded, and FIG. 2 is an external appearance view of such a state that it was opened. In this foldable type portable communication terminal apparatus 1, a lower side housing and an upper side housing 3 are coupled by a hinge mechanism 4. On an inside surface of the lower side housing 2 (a surface which hides when it was closed), various operation keys 5 are disposed, and on a side portion, an antenna 6 is disposed, and on the lowermost portion, a through-hole 7 for a telephone microphone is disposed. On an inside surface of the upper side housing 3 (a surface which hides when it was closed), a main display section 8 is disposed, and on the uppermost portion, a through-hole 9 for a telephone receiver is disposed, and on the inside surface and an outside surface which is on an opposite side thereof, as shown in FIG. 1, a sub display section 10 and an incoming call LED 11 are disposed.

On one side of the hinge mechanism 4, an one-push button 12 is disposed, and when this one-push button 12 is depressed, the hinge mechanism 4 is opened, and comes from a state of FIG. 1 into a state of FIG. 2.

FIG. 3 is an exploded view of the foldable type portable communication terminal apparatus shown in FIG. 1, and FIG. 4 is a cross-sectional view of the one-push button 12 portion of this foldable type portable communication terminal apparatus. As shown in FIG. 3, the lower housing 2 is disposed so as to be divided into a lower case 2 a and a lower cover 2 b, and between the lower case 2 a and the lower cover 2 b, a substrate 23 for mounting electronic components and a key sheet 14 are sandwiched, and an antenna 6 is incorporated into a side portion.

Both end portions of the hinge mechanism 4 are supported by bearing sections 15, 16, respectively, and one bearing section 15 is coupled to the one-push button 12. Respective bearing section 15, 16 are stored in bearing storage sections 2 c, 2 d which were formed so as to be evaginated on top end both sides of the lower cover 2 b.

On a pertinent position of the substrate 13 which corresponds to a position of the key sheet 14 where a talk key 5 a is disposed, LED 17 for the talk key, which has the talk key 5 a lighted up or blinked, is disposed.

As shown in FIG. 3 and FIG. 4, one side of the substrate 13, on which the one-push button 12 is disposed, is formed so as to be extended up to an one-push button mounting position, and on a fore-end portion of an extended portion 13 a, LED 18 for the one-push button, which is used for lighting or blinking display of the one-push button, is disposed. Then, a light guiding hole 19 is formed in a bottom surface of the above-described bearing storage section 2 c which was formed so as to be evaginated, and emitted light of LED 18 passes through the light guiding hole 9 and is guided to a back surface side of the one-push button 12. The one-push button 12 is molded by a milk-white diffusing material, and is configured in such a manner that, when light was guided in the back surface side, the entire one-push button 12 shines.

FIG. 5 is a block diagram of an electric control system which was mounted on the foldable type portable communication terminal apparatus shown in FIG. 1. On the substrate 13, a circuit control section 21, a wireless communication circuit 22 and an opening/closing detection switch 23 which were connected to this circuit control section 21, are disposed, and a telephone receiver 24 which is disposed on a back surface side of the through-hole shown in FIG. 2, and a telephone microphone 25 which is disposed on a back surface side of the through-hole 7, are connected to the circuit control section 21.

The opening/closing detection switch 23 outputs an opening signal to the circuit control section 21 when the upper side housing 3 and the lower side housing 2 are in such a state that they are opened at a predetermined angle or more, and outputs a closing signal to the circuit control section 21 when it is in a state other than that.

In addition, the LED 11 for an incoming call shown in FIG. 1, and LED 17 for the talk key and LED 18 for the one-push button shown in FIG. 3, are connected to the circuit control section 21, and further, various operation keys 5 including the talk key 5 a are connected to the circuit control section 21. However, since the one-push button 12 in this embodiment is disposed only for the purpose of simply opening the hinge mechanism mechanically, there is no electric connection of the one-push button 12 and the circuit control section 21.

FIG. 6 is a flow chart which shows processing procedures of the circuit control section 21 at the time that there was an incoming call. When there is an incoming call (step S1), the circuit control section 21 detects opening/closing of the housing (step S2). That is, it judges whether the opening/closing detection switch 23 is outputting the opening signal or the closing signal.

In case that the opening/closing detection switch 23 is outputting the closing signal and the housing is closed, LED 15 for the talk key 5 a is remained OFF (step S3), and then, LED 18 for the one-push button 12 is turned ON (step S4). In such a state that the foldable type portable communication terminal apparatus 1 was folded, a surface on which the operation keys 5 were disposed is hiding, and therefore, even if the talk key 5 a is lighted up, battery power consumption becomes waste, and therefore, LED 17 is remained OFF, and LED 18 for the one-push button 12 is turned ON, to urge a user to push the one-push button 12.

After LED 18 for the one-push button 12 was turned ON, it waits for such time that the housing is opened (step S5). That is, it waits for such time that the opening signal is outputted from the opening/closing detection switch 23. When a user depresses the one-push button and the housing is opened, the opening/closing detection switch 23 outputs the opening signal, and the circuit control section 21 receives this opening signal to firstly turn off LED 18 (step S6), and starts a talk over the phone by use of the wireless communication circuit 22 (step S7) That is, in this embodiment, a talk over the phone starts when there is an incoming call and the housing is changed from “closing” to “opening”, and thereby, depression of the talk key 5 a becomes unnecessary.

In case that the housing is opened when there was an incoming call (step S1), LED 17 for the talk key 5 a is turned ON (step S8), and LED 18 for the one-push button 12 is remained OFF (step S9). Since the talk key 5 a is lighted up and the one-pushbutton 12 is remained no-lighting, it becomes possible for a user to easily judge that a next operation for carrying out a talk over the phone is depression of the talk key 5 a.

Next, the circuit control section 21 detects again an opening/closing state of the housing (step S10), and if the opening signal is outputted from the opening/closing detection switch 23, it judges whether the talk key 5 a was depressed or not this time (step S11). In case that the talk key 5 a is not depressed, it goes back to detection processing of an opening/closing state of the housing (step S10), and in case that the talk key 5 a was depressed, LED 17 is turned OFF, i.e., lighting is turned off (step S12), and thereafter, it enters into talk processing (step S7).

In case that it was judged that the housing is closed in detection processing of an opening/closing state of the housing (step S10), i.e., in case that there is an incoming call in such a state that the housing was opened and a user closed the housing, in this embodiment, lighting for the talk key 5 a is turned off (step S3) and lighting for the one-push button 12 is turned on (step S4). Then, when the housing is opened again (step S5), lighting for the one-push button 12 is turned off (step S6), and thereafter, a talk is started (step S7).

In this manner, according to this embodiment, in case that there was an incoming call in such a state that the housing was closed, lighting for the one-push button 12 is turned on to urge a user to depress the one-push button 12, and when the housing is opened, a talk is started without depression of the talk key 5 a, and in addition, in case that there was an incoming call in such a state that the housing was opened, lighting for the one-push button 12 is turned off and lighting for the talk key 5 a is turned on, and therefore, it becomes possible for a user to viscerally judge what should be operated next, in order to start a talk.

FIG. 7 is a view which collected up an opening/closing state of the housing and ON/OFF states of LEDs 18, 17, 11. LED for the one-push button is OFF when the housing is in “opening” and ON when the housing is in “closing”, and turned OFF when the housing was changed from “closing” to “opening”. LED for the talk key is ON when the housing is in “opening” and OFF when the housing is in “closing”, and turned OFF so as for a talk to be started, when the housing is changed from “closing” to “opening”. LED for an incoming call is turned ON at the time that there was an incoming call whether the housing is in “opening” or “closing”, and turned OFF in order for a talk to be started, when the housing was changed from “closing” to “opening”.

FIG. 8 is a flow chart which shows processing procedures of a circuit control section which relates to a second embodiment of the invention. There is such a case that a portable communication terminal apparatus is used by being connected to a hands-free device when a user is driving a car, and there is also such a case that an earphone is used. Processing procedures in the suchlike cases will be hereinafter described.

When there is an incoming call (step S21), opening/closing of a housing is detected (step S22). When the housing is in “opening”, the one-push button 12 is remained OFF (step S23), and lighting for the talk key 5 a is turned off (step S24).

Then, next, it is judged whether a hands-free car-mounted adapter is connected or not (step S25). In case that the car-mounted adapter is connected, it is judged whether a hands-free switch is ON or OFF (step S26). In case that the hands-free switch is ON, LED 17 for the talk key 5 a is turned off, in order to start a talk directly (step S27), and thereafter, it enters into talk processing (step S28).

In case that it was judged that the hands-free switch is OFF (step S26), or in case that it was judged that the car-mounted adapter is not connected (step S25), it is next judged whether an earphone is inserted or not (step S29). In case that the earphone is inserted, it is judged whether an earphone switch is ON or OFF (step S30).

Then, in case that the earphone switch is ON, LED for the talk key 5 a is turned off (step S27), and thereafter, it enters into talk processing (step S28) In case that the earphone is not inserted, it is judged whether the talk key 5 a was depressed or not (step S31). Even in case that it was judged that the earphone switch is OFF (step S30), it is judged whether this talk key 5 a was depressed or not (step S31).

In case that the talk key 5 a was depressed (step S31), LED for the talk key 5 a is next turned off (step S27), and thereafter, it enters into talk processing (step S28). In case that the talk key 5 a is not depressed, it goes back to detection processing of an opening/closing state of the housing (step S22).

In case that there is an incoming call (step S21) and it was judged that the housing is in “closing” (step S22), or in case that there was an incoming cal when the housing is in “opening” and a user once closed the housing and thereby it was judged that the housing is in “closing” (step s22), the one-push button 12 is turned ON (step S32), and lighting for the talk key 5 a is turned off, i.e., LED 17 is remained in a no-lighting state (step S33).

Next, it is judged whether the hands-free car-mounted adapter is connected or not (step S24) In case that the car-mounted adapter is connected, it is next judged whether the hands-free switch is ON or OFF (step S35) In case that the hands-free switch is ON, lighting for the one-push button 12 is turned off (step S36), and thereafter, it enters into talk processing (step S28).

In case that the hands-free switch is OFF (step S35) or in case that it was judged that the car-mounted adapter is not connected (step S34), it is judged whether an earphone is inserted or not (step S37) In case that the earphone is inserted, it is judged whether the earphone switch is ON or OFF (step S38).

In case that the earphone switch is ON, LED for the one-push button 12 is turned OFF (step S36), and thereafter, it enters into talk processing (step S28). In case that the earphone is not inserted (step S37), an opening/closing state of the housing is detected (step S39). Even in case that it was judged that the earphone switch is OFF (step S38), it proceeds on to detection processing of an opening/closing state of the housing (step S39).

In case that the housing was turned into “opening” (step S39), LED for the one-push button 12 is turned off (step S36), and thereafter, it enters into talk processing (step S28). When the housing is remained in “closing”, it goes back to judgment processing of whether the car-mounted adapter is connected or not, and it waits for such time that a user talks over the phone by use of each of the hands-free device or the earphone and “opening” of the housing.

In this manner, according to this embodiment, it becomes possible to carry out talk connection by use of these hands-free device and earphone device in case that the hands-free device and an earphone device are connected, in addition to the first embodiment.

The invention was described in detail and with reference to specific embodiments, but it is apparent to a person with ordinary skill in the art that various changes and modifications can be added without departing from spirit and a scope of the invention.

This application is based upon Japanese patent application No. 2003-080890 filed on Mar. 24, 2003, and its content is incorporated herein as a reference.
